   -p, --port=PORT   Connect to the MPD server on PORT, overriding defaults.
   -q, --quiet       Do not output any response messages.  Only errors (on
                     standard error) or binary data (if enabled) are output.
+  -v, --verbose     Print commands as they are submitted.  If both --quiet

   -b, --binary[=FILE]
                     Output raw binary response data, which is normally not
                     written.  If FILE is specified, the data is written there.
                     Otherwise, --quiet is automatically enabled and the data
                     goes to standard output.
